Genome-wide association studies have identified several type 2 diabetes (T2D) risk loci linked to impaired β-cell function. The identity and function of the causal genes in these susceptibility loci remain, however, elusive. The HHEX/IDE T2D locus i

The sigma(54)-factor controls expression of a variety of genes in response to environmental cues. Much previous work has implicated the nucleotide alarmone ppGpp and its co-factor DksA in control of sigma(54)-dependent transcription in the gut commen

The bacterial nutritional and stress alarmone ppGpp and its co-factor DksA directly bind RNA polymerase to regulate its activity at certain σ70-dependent promoters. A number of promoters that are dependent on alternative σ-factors function poorly i

The RNA polymerase-binding protein DksA is a cofactor required for guanosine tetraphosphate (ppGpp)-responsive control of transcription from sigma70 promoters. Here we present evidence: (i) that both DksA and ppGpp are required for in vivo sigma54 tr

Some promoters, including the DmpR-controlled sigma(N)-dependent Po promoter, are effectively rendered silent in cells lacking the nutritional alarmone (p)ppGpp. Here we demonstrate that four mutations within the housekeeping sigma(D)-factor can rest

Pseudomonas-derived regulators DmpR and XylR are structurally and mechanistically related σ54-dependent activators that control transcription of genes involved in catabolism of aromatic compounds. The binding of distinct sets of aromatic effectors t

The activities of promoters can be temporally and conditionally regulated by mechanisms other than classical DNA-binding repressors and activators. One example is the inherently weak σ(70)-dependent Pr promoter that ultimately controls catabolism of

Divergent transcription of a regulatory gene and a cognate promoter under its control is a common theme in bacterial regulatory circuits. This genetic organization is found for the dmpR gene that encodes the substrate-responsive specific regulator of
